Specification of Letters Patent.

- PatentedNov. 13,1917.

Application filed June 21, 1915. Serial No. 35,192.

To all whom it may concern:

Be it known that we, CHARLns' Donnnvc, Jr.,'and HENRY H. DonRINo, citizens of the United States and residents of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Liquid-Dispensing Devices, of which the following is a description, reference being had to the accompanying drawing, which forms a partof our specification.

The object of our invention is'to provide a device whereby liquid may be dispensed in measured quantities from a suitable container or bottle by the'simple or ordinary manipulation of suitable valve-mechanism without the necessityof any particular operation of the valve-mechanism.

Another object of the invention is the provision of a construction wherein certain elements or means may be set or adjusted so as to dispense predetermined or given quantities with each adjustment, so that each operationof the valve-mechanism will dispense a uniform quantity, the advantages of the construction above recited, and others inherent in the construction will be apparent from the detailed description hereinafter set forth.

In the drawing:

*Figure 1 is a partial side and partial. ver tical sectional View of our improved device, with a liquid-container or bottle showninverted into'place.

Fig. 2 is an enlarged longitudinal sectional view of the intermediate or quantitycontrolling portion of the construction shown in Fig. 1.

Fig; 3 is a cross sectional plan view of the liquid-conduit portion of the device, taken approximately along the line 33 of Fig. 2.

Fig. 1 is a detail view of the upper end of the air-inlet portion or tube ofthe device. Fig. 5 is a cross sectional detail'view of the valve-stem or guide-portion.

-The particular exemplification of themvention, as illustrated in the drawing, comprises a suitable base-portion 10, constructed so as to maintain the device in an upright position, and provided at one side with an extended ledge 11 adapted to receive any slight leakage or drip from the discharge or spout 12, which extends out fromthe side of the base 10 at a point suiiiciently above the lower part of the base, to permit the placing of a suitable cup or receptacle 18 beneath the spout. The spout 12 has pivoted to it, preferably'at the point 1 1, a suitable bell-crank lever 15, the lower or outer end whereof terminates in or is provided with a tray-portion 16 adapted to receive theglass or cup 13; while the other end or portion of lever 15 extends lengthwise within the spout 12 to a point in proximity to the stem 17 of a valve 18. V

In the construction illustrated, the spout 12 18 provided with the upwardly presented flange portion 12*, which is provided with a'suitable valve-seat for-the valve 18. The outer circumference of the portion 12- is shown threaded to receive the tubular holdmg-portion or member 19 whichis madeof suitable length to receive the regulatingmechanism as well as the neck of the inverted container or bottle 20. The upper end of theholding-portion 19 is preferably flared, as shown, and at a proper point, in-

termediate of its ends, is provided witha flange or shoulder 21 which provides a'rest or stop for the annular flanged memberor portion 22 of the liquid-conveyingconduit of the device, whereby the liquid is con veyed from the bottle 20 to the liquid-receiving chamber 19 see Fig.1. I Y The disk or annularportion 22is provided with a suitable number of openings-23 for the passage of air, and is preferably made integral with the tubular member or conduit 21, whereby the liquid is conveyed from the container or bottle 20 into the measuring-chamber 19 of the device.

The container or bottle 20 may be 'provided with a suitable'stopper 25'if desired, preferably made of rubber and adapted to fit about the neck of the bottle, as shown in Fig. 2. The stopper; 25 isshown provided with a suitablespring-controlled valve'26 which normally *closes the passage through the stopper, the valve 26being guided and maintained in proper alinement' by suitable guide-rods 27, which also provide a bearingpoint for the inner end of the spring 28. The guide-rods 27 are shown properlyembedded in the rubber stopper 25, so as to maintain the proper relation between the body portion 25 and the valve 26.

The conduit 2 1 is preferably provided with a longitudinally extending diaphragm or wall 2% which, together with oneqside wall of conduit 24, is preferably extended beyond the upper end of the conduit 21 to constitute an air tube or duct '24", as

shown in Fig. 2. The upper end of duct 24 is preferably serrated, as shown at 24, so as to permit the tube or duct 24 to contact with the valve 26 and, at the same time,

permit of the passage of air therethrough and into the bottle or container 20. The upper end of the main portion of conduit 24 is also slightly extended above the portion 22 so as to extend into or form a tight connection with the opening in stopper 25, as shown in Fig. 2.

The lower depending portion of conduit or tubular member 24 is preferably externally threaded to receive the regulating element 29, preferably made to leave space for the passage of air between it and the side walls of the holding-portion 1-9. The regulating member 29 is preferably of the hollow cylindrical construction shown in Figs. 1 and 2 and provided with the inner wall 29 so as to provide the inner chamber or space 30 open only at the bottom end thereof; the inner and outer walls of the device 29 being preferably united above the chamber or space, as shown, and provided with a threaded opening for the passage of the tubular member 24. The space or chamber 30 is adapted to receive the upwardly presented stem 31 of the valve 18. The stem 31 preferably terminates in the diskportion or head, as shown, adapted to close the lower orifice of the conduit 24 when valve 18 is lifted off its seat.

The operation of our device is as follows: A container or bottle provided with the desired liquid is preferably first provided with the valved stopper 25 and then inverted into the holding portion 19 by forcing the bottle downward until the stopper 25 is'in firm contact with the upper end of the main portion of conduit 24. Forcing the bottle downwardly, as described, will bring the airconduit 24 into contact with the spring-controlled valve 26 thereby forcing the latter upward against the action of its spring, into the neck of the bottle together with the air-conduit 24 as shown in Fig. 2. l/Vith regulating member 29 made so as to permit passage of air inter mediate of member 29 and the wall of the holding portion 19, it is evident that air may flow from the air-space within .holding member 19, through the openings 23, between the wallsof member 29 and the holding member 19 and into chamber or space 30, thus allowing the air to be conducted from this point by means of airtube or duct 24 into the bottle. Admitting air into the bottle will permit liquid to flow through the main portion of conduit 24 into the liquid-receiving chamber 19 in the lower portion of holding member 19, as shown in Fig. 1. As soon. as the liquid in chamber 19 rises to a point slightly above the lower portion of member 29, it

is evident that the further flow of air into chamber or space 30 will be prevented. As soon as the air in space or chamber 30, beneath the lower end of tube 24, has ex hausted through tube 24 into the bottle to such extent that the liquid flowing into chamber 19*, and therefore into space 30 covers the lower end of tube 24, further flow of liquid from the container or bottle 20 will be automatically shut 01?. The manipulator may then place the cup or glass 13 on the tray-portion 16 beneath discharge or spout 12, tilt lever 15 so as to force valve 18 upward from its seat which will cause the upwardly presented stem 31 to close the lower orifice of conduit 24; it being understood, of course, that the normal space between stem 31 and conduit 24 preferably corresponds with the distance or degree of movement permitted bell-crank lever 15. The unseating or lifting of valve 18 will permit the liquid which has entered cham ber 19 to flow out through discharge or spout 12 and into the cup or vessel 13; such discharge'being permitted by reason of the fact that the air-space surrounding member 29 is constantly open to the air-space or'chambe'r in holding-portion 19 above the regulating device 29. In order to secure all of the liquid that has entered the chamber 19*, it is necessary for the manipulator to continue to hold-the lever 15 in its tilted position; in fact the Weight of the cup or glass 13 and its liquid contents may, of itself, maintain lever 15 in tilted position. It is evident from the construction shown and described that a constant or uniform quantity of liquid will be obtained with each manipulation of the valve; and if the quantity to be obtained with each manipulation is to be increased or decreased, it may be accomplished by screwing member 29 upward or downward, as the case may be on the conduit 24. 7

Our improved device is especially intended to measure out predetermined quantities of the desired liquid to be dispensed by the device with each operation of the valvemechanism without requiring special operation or manipulation by the operator.
